INK-ERASER.

QPECIPICATIO t? forming part of Letters Patent No. 313,717, dated March10,1885. I

(No model.)

I 0 all whom it may concern:

Be it known that I, \VILLIAM L. FINLEY, a citizen of the United States,residing at Wash ington, in the District of Columbia, have inventedcertain new'and useful Improvements in Ink-Erasers, of which thefollowing is a specification,reference being had to the ae-' companyingdrawings.

My invention relates to devices for erasing from writing, drawing, orother kinds of paper the marks, spots, or stains made by ink orotherwise, and which cannot be removed by the ordinary caoutchouceraser.

The purpose of the invention is to provide a simple and comparativelyinexpensive device whereby the erasure may be easily and quickly madewithout injuring the surface of the paper, which will act equally uponthe same at all points, and which may be used with equal facility by anyperson without the exercise of any skill or special care. It is also mypurpose to provide the erasing-tool with an edge or surface which may beused as a glazing device for restoring the calendered surface of thepaper where it has been abraded by the eraser.

My invention consists in the several novel features of construction andcombinations of parts hereinafter fully described, and definitelypointed out in the claim annexed to this specification.

Referring to the drawings forming part of this application, Figure 1 isa front elevation of the eraser. Fig. 2 is a side or edge view of thesame.

In the drawings, the reference-1etter A indicates the blade of theinstrument, which con sists ofa thick strip ofsteel ofa suitable width,and curved slightly to give a convex surface upon one of its flat sides.This convex face is provided with a series of transverse knifeedges. a,set closely together and rising but very slightly above the surface ofthe blade. A certain pitch or inclination is preferably given to theseknife-edges, whereby they will more readily cut or bite into the paperupon the forward stroke; but this may be varied, or

' even omitted alt0gether,as it does not form an absolutely essentialfeature of my invention.

The end of theblade A is rounded off, as shown in Fig. 1, and the thickedge is polished, there by rendering it capable of use for the purposeof glazing the surface of the paper after the erasure is completed. Theblade A is set in a suitable handle,'B, and is used by placing theconvex surface upon the paper and n1oving it back and forth in thedirection of the length of the blade.

What I claim is- As an article of manufacture, an ink-eraser consistingof a blade curved to give convexity to one of its flat surfaces, andprovided with knife-like edges arranged transversely upon said convexsurface and close together, the end of the blade being rounded andpolished upon its edge to form a glazing-surface, substantially as setforth and specified.

In testimony whereof ,I atlix my signature in presence of two witnesses.

\VILLIAM L. FINLEY.
